Answer:

-5.11

Step-by-step explanation:

as the sum of these numbers is -46 so divide -46 by how many numbers are there for eg:

if there are 5 numbers

20,30,40,50,60

so find the sum of these numbers and divide by 5

as their are 5 numbers

so in our case we have to divide -46 by 9 as there are 9 numbers so our answer is -5.11

How do I figure out which lines or segments are parallel in a equation?

djyliett [7]

Parallel lines have the same slope. So if a line has a slope of 2, a line parallel to it also has a slope of 2.

Find the slope of the line between the points (4,1) and (8,9)

Liono4ka [1.6K]

Use the slope formula which is;
slope= (y2 - y1)/ (x2 - x1)
slope= (9-1)/ (8-4)
Slope= (8)/(4)
Slope= 2

Find the equation of an exponential function in the form y = ab^x, given the points (0, 3) and (2, 108/25). Please simplify your

lilavasa [31]

We have the equation:

$y=a\cdot b^x$

We know two points and we will use them to calculate the parameters a and b.

The point (0,3) will let us know a, as b^0=1.

$\begin{gathered} y=a\cdot b^x \\ 3=a\cdot b^0=a \\ a=3 \end{gathered}$

Now, we use the point (2, 108/25) to calcualte b:

$\begin{gathered} y=3\cdot b^x \\ \frac{108}{25}=3\cdot b^2 \\ 3\cdot b^2=\frac{108}{25} \\ b^2=\frac{108}{25\cdot3}=\frac{108}{3}\cdot\frac{1}{25}=\frac{36}{25} \\ b=\sqrt[]{\frac{36}{25}} \\ b=\frac{\sqrt[]{36}}{\sqrt[]{25}} \\ b=\frac{6}{5} \end{gathered}$

Then, we can write the equation as:

$y=3\cdot(\frac{6}{5})^x$

Which shows the equation below written in the form ax2 + bx + c = 0? 2x2 - 3 = -6x - 2

zmey [24]

Answer:

C. 2x² + 6x - 1 = 0

Step-by-step explanation:

2x² - 3 = -6x - 2

2x² - 3 + 6x = -6x + 6x - 2

2x² - 3 + 6x = -2

2x² - 3 + 6x + 2 = -2 + 2

2x² + 6x - 1 = 0

Hope that helps.
